Abstract

A method of controlling the power delivered by a heterojunction bipolar transistor power amplifier receiving an input power and delivering an amplified output power in a zero intermediate frequency architecture includes a step of detecting the output power and varying a control voltage of the power amplifier by means of a control loop and a step of varying the input power level of the power amplifier.
